Deposition of aerosol particles in vertical channels from an isotropic turbulent flow

Equations for the rate of turbulent deposition of aerosol particles in vertical tubes are suggested. It is noted that the rate of deposition of particles is determined by the gravitation component and turbulent diffusion. The thickness of the layer of depositions and its influence on the basic chara...

Description
Summary:Equations for the rate of turbulent deposition of aerosol particles in vertical tubes are suggested. It is noted that the rate of deposition of particles is determined by the gravitation component and turbulent diffusion. The thickness of the layer of depositions and its influence on the basic characteristics of a turbulent flow are determined. The results obtained are compared with available experimental values of the rate of deposition of particles in vertical tubes.
